Document Table of Contents Using RX in Adaptive Mode

When CTLE, VGA or DFE is in adaptive mode, you must use reconfiguration to access the Avalon® memory-mapped interface and reset and start the adaptation.

You can refer to section Adaptation Control - Start and Adaptation Control - Stop to start and stop the adaptation. Ensure that RX PMA is out of reset and rx_analogreset_stat is deasserted before starting adaptation. The adaptation engine converges the values within 50 ms.

Refer to the RX PMA sections of the Logical View of the L-Tile/H-Tile Transceiver Registers for more details on the register addresses, and the Intel® Stratix® 10 Dynamic Transceiver Reconfiguration chapter for details on the Avalon® memory-mapped interface and how to perform dynamic reads and writes to the analog PMA settings.
